Management of Flood and Drought through Development of Water Resources in Odisha State

Abstract

In the state of Odisha calamities like drought and flood were repeated events. They usually have a direct connection with space and volume. High rainfall causes the flood and low rainfall drought. As per the state water commission reports the per-capita availability water in 2001 was 3359 m3. Because of climate changes and uncertainty of monsoons by 2051 water is likely going to decrease 2218 m3 (Source from Water Resources of Odisha Regional Centre for Development Cooperation). Growing of population, industries and other activates like mining, urbanisation the water requirements are raising, but recourses are shrinking day by day. All over the state rainfall is not equally spreading a few areas receiving abundant and remaining are low for the reason that floods and droughts are usually occurring. More and more reservoirs are essential to store flood water and supply to less precipitated drought areas. So in this paper mainly focusing on flood management through flood control structures like embankments, check dams and improvement of reservoir storage capacity by using effective rule curves and methods recommended as technical strategies to develop the water resources to minimise the drought.
